IMPROVEMENT IN 'MACHINES FOR SAWING SHINGLES.

Specification forming part of Letters Patent N0. 206,775, lated August(i, lerl; application tiled April9, 1878.

To all 107mm it may concern Be it known that I, MATTHEW F. CONNETT, ofDevalls Bluif, in the county of Prairie and State of Arkansas, haveinvented certain new and useful Improvements in Shin gie-M aehines 5 andI do hereby declare that the following is a full, clear, and exactdescription thereof, which will enable others skilled in the art towhich it appertains to make and use the same, reference beinghad to theaceomp. nying drawings, which form a partl of this specification, and inwhich- Figure l is a perspective view. Fig. 2 is a Fig. 3 is atop viewof the machine, the rotating disk or table having been removed. Fig. 4is a vertical diametrical section, and Fig. 5 is a section after theline x a, Fig. 3.

Similar letters of reference denote corresponding parts in all thefigures.

This invention appertains to certain improvements in shingle-machines;and it consists, first, of a frame, having a bed-piece combined withslides, vertical adj ustable shafts or arbors having saws, and rotatingdisk or table having slots; and, secondly, of the peculiar arrangementand adjustability of two or more saws with reference to a rotating tableor disk having means for holding the bolts, held in place byspring-clamps operated upon by releasing mechanism, substantially ashereinafter more fully set forth.

A is the frame of the machine, which consists of a table or bed, B,supported upon legs or uprights a a, secured in a bottom piece, A. S isa central shaft, provided with a cone pulley, P, and having its bearingsin the bottom piece A' and bed B, above which latter it projects,carrying the rotating disk or table C. The latter, which is elevatedabove bed B by a spacin g-disk, C', is of considerable thickness, andhas a number of radial slots, D D, cut from the periphery toward thecenter, and which form the feed-boxes.

b b are spring-clamps, arranged in suitable bearings upon the sides oftable C in such a manner that their front ends, which are curved, areforced into the slots or feed-boxes D D.

In the sides of the bed-piece Bare arranged two upward-projectingmetallic hooks or bent rods, R R, against which the rear ends of thespring-clamps b b strike when the disk rotates,

thus momentarily releasing the hold of the clamps upon the bolts in thefeed-boxes.

The hed B has, on diametrieally-oppositc sides, wide slots G G, on oneside of each of which is arranged a slide, H, forming the upper bearingfor one of the saw-shafts, K K, the lower bearings ot' which are in thebottom piece A. One end of the slides HHprojects into the bed B, asshown at 7L, Fig. 5; and the other (outer) end of each of the slides isforked, and supported upon a set-screw, L, which admits of the slidebeing moved and adjusted laterally, tlms enabling the shafts K K to beadjusted slantin gl y toward or from the center of the bed.

The shafts li K are provided with fixed pnlleys M M, and at their upperends they carry the horizontal circular saws N N. It will be observedthat by slanting the shafts in the manner described the saws may be setor ad justed at any desired angle to the bed of the table,usually atanan gle of about four degrees. It will also be seen that one of the sawsis set to slant down toward the center of the table, while the one onthe opposite side slants down toward the periphery.

I may also here state that in large machines four, six, or even eightsaws may be used, the saws being in such case set to slant alternatelytoward the center and the periphery. The number of slots or feed-boxesin the rotating disk O may also be varied, according to the size of themachine.

My improved shin gle-machine maybe operated by any suitable motivepower, from the counter-shaft of which belts are run to the shafts S KK. By means of the different diameters of the cone pulley upon shaft S,the revolving table C may be rotated at any deA sired degree of speed.Previous to starting, the bolts, which are required to be cut up intoshingles, are placed in the feed-boxes D, in which they are firmly heldbythe spring-clamps b b, their under sides resting upon the bed B, thedistance between which and the rotating table is somewhat more than thethickness of a shingle. As the table rotates the bolts are successivelypresented to the saws. The first of these, being set slanting toward thecenter, ents a shingle off the bolt with the butt to ward the periphery.As soon as the saw 1s passed the springvelamp l strikes` the hook or rod1t, thus releasing the bolt, which talls down upon the bed B. The nextsaw which is reached slauts toward the periphery. lt thus cuts a shinglewith the butt toward the center. When the saw is passed the bolt isagain released by the clamp b striking the releasing-rod R, thus causingthe bolt to assume, antomatieally, the proper position for the next saw.

My improved shingle-machine performs its work with great exaetuess andaccuracy, and, owing to the t'aet that the rotating table may have acomparatively great number oi' feed-boxes. with great rapidity. It issimple iu construction. eonsisting ot' lult t'ew parts. The saws may bereadily set to eut shingles ot' varying slant, and may, when set level,be employed for eutting bo\stutil and other small lumber; and, finally,the feeding meehanism being entirely automatic, it requires but littleattention.

Having thus described my invention, I claim and desire to seeure byLetters latent of' the l'nited States- The combination of the frame A,having bed-pieee B, slides 1l H, adjustable vertical shafts 1( K, havingsaws N N, and rotating disk or table U, having slots I) I), all arrangedand operating substantially as described, for the purpose herein setforth.

L. The combination, in a rotary shin glemachine, ot' two or more saws,arranged alternately slanting toward and from the center ofthebed-piece, with a rotating disk or table having slots forming'feed-boxes, in which the bolts are held by spring-clamps, and mechanismt'or releasing the latter after the feedboxes have passed the saws, s0as to eause the bolts to be fed automatically by their own weight,substantially as herein deseribed, t'or the purpose shown and specified.

1n testimony that I elaim the foregoing as my own l have hereto atiixedmy signature in present-e ot' two witnesses.
